Today I’ve got some interesting messages, that my code was identical to some other participants code.

My C solve: 265996712

Other's C solve: 266045067

My D solve: 266022195

Other's D solves:

266029086

266030481

266031091

266031520

266034835

266038553

266039854

266044066

266044752

266045672

Actually, these solutions on both problems are completely same to mine. This can’t be an accident, so this solutions are copied from me. Since I didn't give my solution to anyone, and didn't keep the code publicly available, this could only happen if one of the participants solved the problem, blocked it, copied my code, and sent it to his friends.

In my room 3 participants(excluding me) solved C and D, but only one blocked them both. It’s Motherhacker123. Also he solved only C and D not even trying for A and B, which is quite strange, since the round was rated for him. Also all the submissions of participants from the list were sent after he blocked his task.

This method of cheating at contests allows the person who sends solutions to everyone to remain unpunished, and all the punishment goes to another honest participant.

Please look at this problem,MikeMirzayanov
